I worked like a dog

On my homework last night

I fetched all my homework last night

Then took a humongous bite

I solved some equations but my brain fried

I licked everyone

Then buried the worksheet with my brains

When it was done

My science exhibit was done

I got a glass jar

I filled with fleas

I worked like a dog last night

With hopes to impress

But something went wrong

'cause my homework's a mess
